My invention relates to the novelmmns f destroyingr insects, caterpillars, vermin and other pests in inaccessible places, such as, topsof trees, eaves of houses; also to the destruction of hornets nests, bumble bee nests, etc. L

vMy invention is particularly directed to eaterpillar tents and nests of moths and insects which do considerable damage to trees and vegetation, and which are often left unattendedl and undestroyed because of the diculty and inconvenience in reaching them. My invention relatesf to a convenient method of effecting their destruc-a tion by the use of shot gun shells, which have the usual charge of powder but instead of having the shot .incorporated therein will incorporate' therein sand, gravel,v insecticide powder. sand soaked in kerosene or mixed with ammable powders, oils, etc. The discharge of the gun would ignite the flammable material about the sand or gritty particles and carry to theobpect to be destroyed, the purpose being to have the sand pit the structureabout the nests and carry some of the insecticide and iammable material to the surrounding nesting material.

I may prepare these shells without the ammable material and limit to a gritty substance and the insecticide, or I may coat the gritty substance with liquid insecticides mixing the gritty substance with a ammable powder and other insecticide, or I may mix the gritty substance with ammable oils and substances which will ignite the nest webs. I have particularly in mind the tent worm, which weaves a web and deposits therein its eggs, permitting the same to 'be hatched inside the gauze-like substance spun by the parent. Likewise undesirable nests or webs of various insects which may be formed in trees or otherwise. Y

My shells are prepared in much the same way as ordinary shells' except that instead of being lled with lead or shot in some cases they would be lled with sand, in other cases with granular insecticide powder, and still others would be lled with mineral matter coated with oil, or a combination of the above. As far as expelling the contents of the shell is concerned the face of the shell would be constructed lmuch the same as ordinary shells; the upper housing would contain the destroying chemicals andsand or gritty substance as a means of impressing those chemicals in the surrounding surface. In this manner the tent housing and these various nests may be destroyed from the ground, torn open and sprayed with insecticide, much more conveniently and readily than attempting to burn them out with' that shown in Figure l.

.shell casing is divided into a plurality of chamtorches and' involving other risks in their destruction.

One of the features of my invention is to provide a means whereby the substance in the shell may ash on its way to the mark and in this manner cause fumes to be present at the'time of contactwith the mark. -Or I may use afuming cotton batting or other pellets which would adhere to the surrounding surface when shot, causing the. seme to fume and emit the fumes, thus `also destroying these insects. p

My invention relates to the no vel means of `providing a shell much the same as a shot gun shell,- having an explosive cap, a chamber for chamber for the insecticides, either singly or` in l combination.

My invention may be illustrated by reference to the accompanying drawing wherein Figure 1 is a longitudinal sectional view of one embodiment thereof, and Figure 2 is a corresponding view of a diierent embodiment thereof.

In Figure'l is shown a shell casing i provided with an end closure '2, with an explosive cap 3 disposed centrally thereof. A chamber is formed on the interior of theshell adjacent the detonatingvcapfor receiving an explosive charge t. The remainder of the shell is formed as a chamber 5 which may be closed by the disk S for receiving a mixture as disclosed above which may be a moist 30 M1.. xture oi granular material and insecticide material with or without the addition of an inamniable material.

In Figure 2 is shown a shell casing similar to In this instance, the

here, such as i5 and it, by a spacer disk i1; In the Vchamber i@ may be disposed they granular material for impelling the insecticide material disposed in chamber i5.

Having thus described my invention what I claim is: v

l.. A shell adapted to be discharged into places infested with undesirable animal life containing a mixture of granular material soaked in an inammable medium with a vermin-destroying agent, and an explosive charge for propelling said mixture into such places.

2. A shell containing a mixture of a moist granular material coated with a vermin-destroying agent and an iniiammable medium, and an explosive charge for propellingsaid mixture.

3. A shell containing a mixture of gritty material coated with a liquid insecticide and an inpowder, a chamber for the gritty sand and a .l5

4. A shell containing a mixture -ot a granular material soaked in an inflammable medium with I a powdered insecticide, and an explosive charge for propelling said mixture.

5. A shell containing a mixture of granular material coated with a liquid insecticide, an inilammable powder and a powdery vermin-destroying agent, and an explosive charge for propelling said mixture into space.

6. A shell containing a'moist mixture of granular material coated with an inflammable medium and an insecticide, and an explosive chargefor propelling said mixture into space. y

7. A shell comprising an explosive cap and provided with a chamber adjacent to said 'cap containing an explosive charge,l a second chamber adjacent to said ilrst chamber containing granular material and a third chamber adjacent to said second chamber containing insecticide materialy8. A shell comprising explosive cap and provided with a chamber adjacent to said cap containing an explosive charge` and a second chamber adjacent to said iirs't chamber containing a moist mixture oi' granular material, inilaminable l material and a vermin-destroying' agent.

9. A shell containing a' mixture Ioi! granular material with a vermin-destroying agent, Vfume emitting pellets in said mixture adapted ,to give oil fumes which are poisonous to said vermin,

and an explosive charge in said shell for propell-` 1 ing said mixture and pellets into space.

10. A shell containing a mixture. of granular material with an insecticide, cotton batting incorporated in said shell adaptedto'emit fumes poisonous to insects uponthedischarge otsaid mixture, and an explosive charge in said shell'for propelling said mixture and'rcotton batting ,into space. f'
